2023-08-28octeontx2-af: print error message incase of invalid pf mappingHariprasad Kelam1-0/+5
During AF driver initialization, it creates a mapping between pf to cgx,lmac pair. Whenever there is a physical link change, using this mapping driver forwards the message to the associated netdev. This patch prints error message incase of cgx,lmac pair is not associated with any pf netdev.

2023-08-28octeontx2-af: CN10KB: Add USGMII LMAC modeHariprasad Kelam2-0/+2
Upon physical link change, firmware reports to the kernel about the change along with the details like speed, lmac_type_id, etc. Kernel derives lmac_type based on lmac_type_id received from firmware. This patch extends current lmac list with new USGMII mode supported by CN10KB RPM block.

2023-08-28netrom: Deny concurrent connect().Kuniyuki Iwashima1-0/+5
syzkaller reported null-ptr-deref [0] related to AF_NETROM. This is another self-accept issue from the strace log. [1] syz-executor creates an AF_NETROM socket and calls connect(), which is blocked at that time. Then, sk->sk_state is TCP_SYN_SENT and sock->state is SS_CONNECTING. [pid 5059] socket(AF_NETROM, SOCK_SEQPACKET, 0) = 4 [pid 5059] connect(4, {sa_family=AF_NETROM, sa_data="..." <unfinished ...> Another thread calls connect() concurrently, which finally fails with -EINVAL. However, the problem here is the socket state is reset even while the first connect() is blocked. [pid 5060] connect(4, NULL, 0 <unfinished ...> [pid 5060] <... connect resumed>) = -1 EINVAL (Invalid argument) As sk->state is TCP_CLOSE and sock->state is SS_UNCONNECTED, the following listen() succeeds. Then, the first connect() looks up itself as a listener and puts skb into the queue with skb->sk itself. As a result, the next accept() gets another FD of itself as 3, and the first connect() finishes. [pid 5060] listen(4, 0 <unfinished ...> [pid 5060] <... listen resumed>) = 0 [pid 5060] accept(4, NULL, NULL <unfinished ...> [pid 5060] <... accept resumed>) = 3 [pid 5059] <... connect resumed>) = 0 Then, accept4() is called but blocked, which causes the general protection fault later. [pid 5059] accept4(4, NULL, 0x20000400, SOCK_NONBLOCK <unfinished ...> After that, another self-accept occurs by accept() and writev(). [pid 5060] accept(4, NULL, NULL <unfinished ...> [pid 5061] writev(3, [{iov_base=...}] <unfinished ...> [pid 5061] <... writev resumed>) = 99 [pid 5060] <... accept resumed>) = 6 Finally, the leader thread close()s all FDs. Since the three FDs reference the same socket, nr_release() does the cleanup for it three times, and the remaining accept4() causes the following fault. [pid 5058] close(3) = 0 [pid 5058] close(4) = 0 [pid 5058] close(5) = -1 EBADF (Bad file descriptor) [pid 5058] close(6) = 0 [pid 5058] <... exit_group resumed>) = ?

Sabrina Dubroca says: ==================== tls: expand tls_cipher_size_desc to simplify getsockopt/setsockopt Commit 2d2c5ea24243 ("net/tls: Describe ciphers sizes by const structs") introduced tls_cipher_size_desc to describe the size of the fields of the per-cipher crypto_info structs, and commit ea7a9d88ba21 ("net/tls: Use cipher sizes structs") used it, but only in tls_device.c and tls_device_fallback.c, and skipped converting similar code in tls_main.c and tls_sw.c. This series expands tls_cipher_size_desc (renamed to tls_cipher_desc to better fit this expansion) to fully describe a cipher: - offset of the fields within the per-cipher crypto_info - size of the full struct (for copies to/from userspace) - offload flag - algorithm name used by SW crypto With these additions, we can remove ~350L of switch (crypto_info->cipher_type) { ... } from tls_set_device_offload, tls_sw_fallback_init, do_tls_getsockopt_conf, do_tls_setsockopt_conf, tls_set_sw_offload (mainly do_tls_getsockopt_conf and tls_set_sw_offload). This series also adds the ARIA ciphers to the tls selftests, and some more getsockopt/setsockopt tests to cover more of the code changed by this series. ==================== Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>

Donald Hunter says: ==================== tools/net/ynl: Add support for netlink-raw families This patchset adds support for netlink-raw families such as rtnetlink. Patch 1 fixes a typo in existing schemas Patch 2 contains the schema definition Patches 3 & 4 update the schema documentation Patches 5 - 9 extends ynl Patches 10 - 12 add several netlink-raw specs The netlink-raw schema is very similar to genetlink-legacy and I thought about making the changes there and symlinking to it. On balance I thought that might be problematic for accurate schema validation. rtnetlink doesn't seem to fit into unified or directional message enumeration models. It seems like an 'explicit' model would be useful, to force the schema author to specify the message ids directly. There is not yet support for notifications because ynl currently doesn't support defining 'event' properties on a 'do' operation. The message ids are shared so ops need to be both sync and async. I plan to look at this in a future patch. The link and route messages contain different nested attributes dependent on the type of link or route. Decoding these will need some kind of attr-space selection that uses the value of another attribute as the selector key. These nested attributes have been left with type 'binary' for now. ==================== Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>

2023-08-27Merge branch 'devlink-mlx5-add-port-function-attributes-for-ipsec'Jakub Kicinski15-108/+898
Saeed Mahameed says: ==================== {devlink,mlx5}: Add port function attributes for ipsec From Dima: Introduce hypervisor-level control knobs to set the functionality of PCI VF devices passed through to guests. The administrator of a hypervisor host may choose to change the settings of a port function from the defaults configured by the device firmware. The software stack has two types of IPsec offload - crypto and packet. Specifically, the ip xfrm command has sub-commands for "state" and "policy" that have an "offload" parameter. With ip xfrm state, both crypto and packet offload types are supported, while ip xfrm policy can only be offloaded in packet mode. The series introduces two new boolean attributes of a port function: ipsec_crypto and ipsec_packet. The goal is to provide a similar level of granularity for controlling VF IPsec offload capabilities, which would be aligned with the software model. This will allow users to decide if they want both types of offload enabled for a VF, just one of them, or none at all (which is the default). At a high level, the difference between the two knobs is that with ipsec_crypto, only XFRM state can be offloaded. Specifically, only the crypto operation (Encrypt/Decrypt) is offloaded. With ipsec_packet, both XFRM state and policy can be offloaded. Furthermore, in addition to crypto operation offload, IPsec encapsulation is also offloaded. For XFRM state, choosing between crypto and packet offload types is possible. From the HW perspective, different resources may be required for each offload type. Examples of when a user prefers to enable IPsec packet offload for a VF when using switchdev mode: $ devlink port show pci/0000:06:00.0/1 pci/0000:06:00.0/1: type eth netdev enp6s0pf0vf0 flavour pcivf pfnum 0 vfnum 0 function: hw_addr 00:00:00:00:00:00 roce enable migratable disable ipsec_crypto disable ipsec_packet disable $ devlink port function set pci/0000:06:00.0/1 ipsec_packet enable $ devlink port show pci/0000:06:00.0/1 pci/0000:06:00.0/1: type eth netdev enp6s0pf0vf0 flavour pcivf pfnum 0 vfnum 0 function: hw_addr 00:00:00:00:00:00 roce enable migratable disable ipsec_crypto disable ipsec_packet enable This enables the corresponding IPsec capability of the function before it's enumerated, so when the driver reads the capability from the device firmware, it is enabled. The driver is then able to configure corresponding features and ops of the VF net device to support IPsec state and policy offloading. v2: https://lore.kernel.org/netdev/[email protected]/ ==================== Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>
2023-08-27net/mlx5: Implement devlink port function cmds to control ipsec_packetDima Chumak6-4/+173
Implement devlink port function commands to enable / disable IPsec packet offloads. This is used to control the IPsec capability of the device. When ipsec_offload is enabled for a VF, it prevents adding IPsec packet offloads on the PF, because the two cannot be active simultaneously due to HW constraints. Conversely, if there are any active IPsec packet offloads on the PF, it's not allowed to enable ipsec_packet on a VF, until PF IPsec offloads are cleared.
